Abstract

Un método de búsqueda de célula en un sistema dúplex por división de tiempo/acceso múltiple por división de código (TDD/CDMA) que utiliza códigos de sincronización primarios y secundarios y que tiene una pluralidad de Nodos B, caracterizado porque el método comprende: la búsqueda de un código de sincronización primario (PSC) y su sincronización , PSC que es común a toda dicha pluralidad de Nodos B; el uso del PSC para ubicar un código de sincronización secundario (SSC), que es único para un Nodo B específico; y la sincronización con dicho SSC. Esto simplifica en gran medida el procedimiento de búsqueda de célula y mejora la performance de búsqueda de célula. En una forma de realización, el Código de Sincronización Primario es enviado al P-CCPCH y los Códigos de Sincronización Secundarios son enviados al segmento de tiempo DwPTS. También se divulga un aparato de búsqueda de célula en un sistema dúplex por división de tiempo/acceso múltiple por división de código (TDD/CDMA) que utiliza códigos de sincronización primarios y secundarios.A method of cell search in a time division / multiple division code access (TDD / CDMA) duplex system that uses primary and secondary synchronization codes and has a plurality of Nodes B, characterized in that the method comprises: search for a primary synchronization code (PSC) and its synchronization, PSC which is common to all said plurality of Nodes B; the use of the PSC to locate a secondary synchronization code (SSC), which is unique to a specific Node B; and synchronization with said SSC. This greatly simplifies the cell search procedure and improves cell search performance. In one embodiment, the Primary Synchronization Code is sent to the P-CCPCH and the Secondary Synchronization Codes are sent to the DwPTS time segment. A cell search apparatus is also disclosed in a time division / multiple division code access (TDD / CDMA) duplex system that uses primary and secondary synchronization codes.
